Application filed May 27,1909. Serial No. 498,759.

Be it known that I, JAMES DAVID Tir'ron,

a citizen of the United States, residing at Coife ville, in the county of Montgomery and tate of Kansas, have invented certain new and useful Improvements in Honing and Stropping Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to machines for sharpenlng razors and other edged tools, and the princlpal object of the same isto provide the machine with a novel type of sharpener carrying mechanism which cooperates with a razor operatmg mechanism so as to assure of the razor being properly sharpened.

, blade.

It will be understood, of course, that in the practical application of the invention, the essential features of the same are susceptible of changes in details and structural arrangements, one preferred and simple embodiment of which is shown in the accompanying drawings, wherein Figure l is .a view in front elevation of" the improved sharpening machine, part of the same being shown 1n section to illustrate the razor-rotating or turning mechanism. Fig. 2 is a top plan view, the sharpener being removed. Fig. 3 is a vertical secstional view, taken on the line 3-3, Fig. 2. 4 is a :rear elevation, part of the same bei broken away to show the iides for thes arpener carrier. Fig. 5 is a diam plan view of the sharpener carrier. Fig. 6 is a detail vertical sectional view taken on the line 66, Fig. 2. Fig. 7 is a similar view taken on the line 77, Fig. 2. Fig. 8 is a. detail sectional view taken on the line 8--8,

Fig. 2. Fig. 9 is a similar view taken on the line 9-9, Fig. 2. Fig. 10 is a. detail broken a view showing the roller for moving the sharpener carrier. 1 7

Referring .to said drawings, it will be seen that the improved sharpening machine end members 1, arranged to form a substantiall rectangular open frame.

T e end members form supports for a f of guide bars orrods 5, said rods pluralit being e ually spaced apart. A caror bars ria e 6 is slida 1y mounted on said .bars 5 w an is guided in its reciprocations b the same. Said carriage carries transverse y arranged end members 7 which are longitudinally grooved as indicated at 8 for the reception of end tongues 9 of a horizontally slidable sharpener carrier 10. Said sharpener carrier 10 is provided with oppositely disposed u stan ing bearing blocks 11 each provide with a vertical slot 12 for the reception of the end. shafts 13 of a sharpening member 14. Said member 14 has four fiat sides which are adapted for honing and stropping, either side of which may be turned up by means of the described manner of mounting the stone. The undersurface of the sharpener carrier 10 is provided with a substantially V-shaped guiding slot 15 which engages with a roller 16 carried by and pro jecting from one of the guiding rods 5. I

The forward ends of the members 4 are each lon itudinally slotted as indicated at 17 and have a similarly slotted block 18 mounted on them the slot of which registers with the slot'in said members. in and guiding rod or bar 19 has its ends he d in adjustable and detachable engagement with the slotted portions of said b ocks and said members by means of the thumb nuts and bolts 2021.- The central ortipn of said rod or bar 19 carries space a art upstandingbearings 22 for a shaft 23 w ich has. mounted on it between said bearings a A support-.

pinion 24. The inner end of said shaft 23 1 by rubber or like yielding material 26. Said jaws are pivotally mounted on said shaft and are held in locked relation by means of a cam lever 27 havin a bail or other iv,- otal connection 28 wit the shaft 23. aid shaft 23 carries a laterally projectlng weighted lug 28" which contacts with acjustable abutments 2930 mounted 1n and rojecting through one ofthe upstandlng Eearin s 22 and arranged on op. osite sides of sai shaft, to limit said she s rotation as will be obvious.

The bearings 22 retain the shaft 23 sufii-- of which is in ries another gear 41 which is in mesh with ciently spaced from the bar 19 so that its pinion 24 may be rotated by a rack-31 slidable on said bar 19 andlbetween said bearings. Said rack has a yoke en agement 32 at one end with said bar 19 and intermediate said K end is provided with a longitudinal slot 33 which extends transversely through the body of said rack and. which is engaged by a connectin member 34 of a pair of crank arms 35 aving a. pivotal connection with one end of a pitman36 the other end ivotal engagement with a crank arm 37 pivotally mounted on acam wheel 38mounted on a shaft 39 supported in bearings 40 carried by the bottom of the frame of the machine. 7 Said shaft 39 cara pinion 42 mounted on a power shaft 43 which carries a larger gear 44 held in mesh with a pinion 45 mounted on a shaft 46 carried by a motor 47. The gear 41 carries a pitman' 48 having a bifurcated end 49 which as a projecting from the underside of the carriage 6.

The crank arm 37 is loosely mounted on the cam wheel 38 andis provided with an iuturned end 51 which projects over the periphery of said wheel and in the path of movement of a cam projection 52thereon so that when said projection contacts with said crank armjthe pitman 36 will be actuated to slide the rack 31 so as to cause the pinion 24.to rotate the shaft 23, and thereby reverse the position of the grip ing jaws '25. Said cam wheel .38 is provi ed with a hub; 53 which fits over-the end of shaft 39, so that said wheel maybe adjusted by means of the spring pressed thumb screw or in 54 which passes through said hub 53 an is adapted for engagement with any one of the opening s 55 formed transversely in said shaft39,

. as is shown more clearly in Fig. 9.

' In operation the razor or other tool or instrument to be sharpened is clamped between the gripping jaws 25 by means of the.

camlever (see Fig. 6) with its blade pro- "ecting acrossthe sharpener. The motor 47 eing operated, the pitman 48. will reciprocate the carrier 6' longitudinall of the frame, and the shar ener carrier s 'dably mounted thereon will e reciprocated transversely of.

said carriage by means of its slot and roller engagement with the guide member 5-, thereby the sharpener' tohave an ellip- Qti'cal movement so as to assure of the blade 1 .reac w; crank arm 37 will be engaged by the probein properl treated. As the carria e Ee's the end of its-longitudinal stroke, t e

"jection '52 of the cam w cal 38 aid cause thl'pitman 36 to, slide the rack while in con- 1 with thep'inion 2 4 on the shaft 23, and

" thereby reverse the position of'the razor 'so a thatifi will be in position to be treated .by

the movement .o'f'the carrier;

ivotal engagement with an ear 50.

across'said sharpener, and means for turning said holder when the carriage reaches the end of its-longitudinal stroke.
